Background Thrombocytopenia is a common clinical problem in neonatal intensive care units, affecting about 20 to 35% of all admitted neonates. Even most episodes are mild or moderate, severe episodes could be life-threatening or responsible for sequelae. Objectives The aims of this study were to describe the prevalence, clinical diagnoses, and to determine risk factors for poor prognosis of thrombocytopenia in a neonatal intensive care unit. Methods We carried out a retrospective study in the neonatal intensive care unit of Charles Nicolle Hospital of Tunis, a tertiary neonatal care center, over a four years period (January 2010 to December 2013)...

OBJECTIVE: In sepsis, the disease course of critically ill patients is often complicated by muscle failure leading to ICU-acquired weakness. The myokine transforming growth factor-β1 increases during inflammation and mediates muscle atrophy in vivo. We observed that the transforming growth factor-β1 inhibitor, secreted frizzled-related protein 2, was down-regulated in skeletal muscle of ICU-acquired weakness patients. We hypothesized that secreted frizzled-related protein 2 reduction enhances transforming growth factor-β1-mediated effects and investigated the interrelationship between transforming growth factor-β1 and secreted frizzled-related protein 2 in inflammation-induced atrophy...

UNLABELLED: Klebsiella pneumoniae is a Gram-negative pathogen responsible for a wide range of infections, including pneumonia and bacteremia, and is rapidly acquiring antibiotic resistance. K. pneumoniae requires secretion of siderophores, low-molecular-weight, high-affinity iron chelators, for bacterial replication and full virulence. The specific combination of siderophores secreted by K. pneumoniae during infection can impact tissue localization, systemic dissemination, and host survival...

Heparanase is implicated in angiogenesis and tumour progression. We previously demonstrated that heparanase might also affect the haemostatic system in a non-enzymatic manner. It forms a complex and enhances the activity of the blood coagulation initiator tissue factor (TF). Peptides that we generated from TF pathway inhibitor (TFPI)-2, which inhibit heparanase procoagulant activity, were recently demonstrated to attenuate inflammation in a sepsis mouse model. The present study was designated to explore peptides effects on tumour growth and vascularisation...

INTRODUCTION: Interleukin (IL)-27 is an important cytokine involved in many human inflammatory diseases. In this study, we investigated its role in the pathogenesis of sepsis-induced myocardial dysfunction (SIMD). METHODS: Twenty patients with SIMD and 24healthy donors were prospectively enrolled. Expression of IL-27 was detected in serum from SIMD patients by ELISA. Cardiac dysfunction was induced by administration of Escherichia coli lipopolysaccharide (LPS) to C57BL/6 (wild type) or IL-27R(-/-) mice...

: Staphylococcus aureus is a human pathogen, and S. aureus bacteremia can cause serious problems in humans. To identify the genes required for bacterial growth in calf serum (CS), a library of S. aureus mutants with randomly inserted transposons were analyzed for growth in CS, and the aspartate semialdehyde dehydrogenase (asd)-inactivated mutant exhibited significantly reduced growth in CS compared with the wild type (WT). The mutant also exhibited significantly reduced growth in medium, mimicking the concentrations of amino acids and glucose in CS...

In current study, we investigated the role of liriodendrin, a constituent isolated from Sargentodoxa cuneata (Oliv.) Rehd. Et Wils (Sargentodoxaceae), in cecal ligation and puncture (CLP)-induced acute lung inflammatory response and injury (ALI). The inflammatory mediator levels in bronchoalveolar lavage fluid (BALF) were determined by enzyme-linked immunosorbent assay (ELISA). Pathologic changes in lung tissues were evaluated via pathological section with hematoxylin and eosin (H&E) staining. To investigate the mechanism whereby liriodendrin regulates lung inflammation, the phosphorylation of the NF-kB (p65) and expression of vascular endothelial growth factor (VEGF) were determined by western blot assay...

UNLABELLED: Bone marrow (BM) is a reservoir for immune and hematopoietic cells and critical for tissue repair and regeneration. All of these functions are severely altered in cirrhosis. We investigated the cellular and functional state of BM in cirrhosis patients. We studied the histological, cellular, and molecular changes in BM of cirrhosis patients (n = 168) and controls (n = 44). Hematopoietic stem cells (HSCs) and associated niche cells, mesenchymal stem cells, Schwann cells, neural fibers, and endothelial cells were evaluated by immunohistochemistry...

Epidermal growth factor (EGF) is a cytoprotective protein that improves survival in preclinical models of sepsis through its beneficial effects on intestinal integrity. Alcohol use disorder worsens intestinal integrity and is associated with increased morbidity and mortality in critical illness. We sought to determine whether chronic alcohol ingestion alters the host response to systemic administration of EGF in sepsis. Six week old FVB/N mice were randomized to receive 20% alcohol or water for 12 weeks. All mice then underwent cecal ligation and puncture (CLP) to induce polymicrobial sepsis...

One of the trademarks of extraintestinal pathogenic Escherichia coli is adaptation of metabolism and basic physiology to diverse host sites. However, little is known how this common human pathogen adapts to permit survival and growth in blood. We used label-free quantitative proteomics to characterize five E. coli strains purified from clinical blood cultures associated with sepsis and urinary tract infections. Further comparison of proteome profiles of the clinical strains and a reference uropathogenic E. coli strain 536 cultivated in blood culture and on two different solid media distinguished cellular features altered in response to the pathogenically relevant condition...

OBJECTIVES: Forkhead/winged helix transcription factor p3 (Foxp3) increases in CD4(+)CD25(+)Treg cells during sepsis; however, related mechanisms are unclear. Our study aimed to explore the possible molecular mechanisms of high expression of Foxp3 in Treg cells during sepsis. METHODS: Sepsis was induced by cecal ligation and puncture (CLP) method. CD4(+)CD25(+)Treg cells were isolated from peripheral blood and identified by flow cytometry (FCM). Treg cells were cultured with or without adenosine, adenosine agonist, adenosine antagonist, SMAD family member 3 (Smad3) agonist (transforming growth factor (TGF)-β1), or C-Jun N-Terminal Kinase (JNK) inhibitor...

Necrotising enterocolitis (NEC) is an uncommon, but devastating intestinal inflammatory disease that predominantly affects preterm infants. NEC is sometimes dubbed the spectre of neonatal intensive care units, as its onset is insidiously non-specific, and once the disease manifests, the damage inflicted on the baby's intestine is already disastrous. Subsequent sepsis and multi-organ failure entail a mortality of up to 65%. Development of effective treatments for NEC has stagnated, largely because of our lack of understanding of NEC pathogenesis...
